Millipede (Geometry Wrapper & Isosurface)

Hello everyone,

I am trying to create a surface using the geometry wrapper and the isosurface components but I would like to make it more ‘‘random’’ and organic rather than something that looks like a metaball surface. I thought of creating an alternating field but I do not know how to embed in the the workflow.
Also the initial workflow was taken from the attached article link but even if using the same workflow the result looks way different. I can not make my surfaces looks so organic as the article.

Any help is appreciated.
